Up to the date of our present survey, however, and for half a century yet to come, these conquests of the Lydian kings in Ionia and Caria amounted to little more than forays for plunder and the levy of blackmail, like the earlier Mesopotamian razzias. They might result in the taking and sacking of a town here and there, but not in the holding of it. The Carian Greek Herodotus, born not much more than a century later, tells us expressly that up to the time of Croesus, that is, to his own father's time, all the Greeks kept their freedom: and even if he means by this statement, as possibly he does, that previously no Greeks had been subjected to regular slavery, it still supports our point: for, if we may judge by Assyrian practice, the enslaving of vanquished peoples began only when their land was incorporated in a territorial empire. We hear nothing of Lydian governors in the Greek coastal cities and find no trace of a "Lydian period" in the strata of such Ionian and Carian sites as have been excavated. So it would appear that the Lydians and the Greeks lived up to and after 600 B.C. in unquiet contact, each people holding its own on the whole and learning about the other in the only international school known to primitive men, the school of war. Herodotus represents that the Greek cities of Asia, according to the popular belief of his time, were deeply indebted to Lydia for their civilization. The larger part of this debt (if real) was incurred probably after 600 B.C.; but some constituent items of the account must have been of older date--the coining of money, for example. There is, however, much to be set on the other side of the ledger, more than Herodotus knew, and more than we can yet estimate. Too few monuments of the arts of the earlier Lydians and too few objects of their daily use have been found in their ill-explored land for us to say whether they owed most to the West or to the East. From the American excavation of Sardes, however, we have already learned for certain that their script was of a Western type, nearer akin to the Ionian than even the Phrygian was; and since their language contained a great number of Indo-European words, the Lydians should not, on the whole, be reckoned an Eastern people. Though the names given by Herodotus to their earliest kings are Mesopotamian and may be reminiscent of some political connection with the Far East at a remote epoch--perhaps that of the foreign relations of Ur, which seem to have extended to Cappadocia--all the later royal and other Lydian names recorded are distinctly Anatolian. At any rate all connection with Mesopotamia must have long been forgotten before Ashurbanipal's scribes could mention the prayer of "Guggu King of Luddi" as coming from a people and a land of which their master and his forbears had not so much as heard. As the excavation of Sardes and of other sites in Lydia proceeds, we shall perhaps find that the higher
